(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

we are given that an electron and a proton have the same KE.We are to compare their phase and group velocity...

2. Relevant equations

3. The attempt at a solution

K=(γ₁-1)m₁c²=(γ₂-1)m₂c²

Now, I found it very problematic to extract the ratio of v₁/v₂ in terms of m₁ and m₂

So,I expanded the γ s binomially where the major contribution comes from the first few terms...It follows that group velocity if proton is much less than that of the electron...

Please tell me if I am correct and sggest any other possible ways...
